DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 246,286, dated August30, 1881.

Application filed October 2, 1880. (Model) To all whom "it may concernBe it known that I, CALEB BRINroN, of Ohicago, Illinois, have inventednew and useful Improvements in Sliding- Door Hangers, of which thefollowing is a specification.

My invention relates to improvements in hangers which are attached tothe doors by means of rods and travel upon a track. The objects of myimprovements are to provide a noiseless and free-movin g carriage, thatcannot be thrown from the track, and also to simplify the constructionof hangers, and thus reduce the expense of the same. I attain theseobjects by the mechanism illustrated in the accompanyin g drawings, inwhich- Figure 1 is a front view of the hangers attached to double doors.Fig. 2 is an end view, showing the door, track, and rollers. Fig. 3

. is a front view, showing a modification in the arrangement of thehangers upon the door. Fig. 4 is a detail view in perspective, showingthe hanger. Fig. 5 is a detail view in perspective, showing adoor-buffer.

Similar letters indicate the several parts of the drawings.

The bracket A, having vertical and horizontal arms, with wheels B androlls B, suspension-rod C, with the angular attaching-plates D, havinglug D, Fig. at, constitute the hanger.

'The square-sided single track E is secured to header F by means ofbolts 0, as shownin Figs. 1 and 2, said header being secured rigidly toand forming a part of the building. The said track E can be raisedorlowered, as may be desired, by means of the nuts J. Thesuspension-rods O, which are slightly flattened to facilitate turningwith a wrench, are fitted loosely within the recessed projections orlugs H of the bracket A, and are threaded upon the lower end, so as tobe turned into corresponding threads in part D of plate D, by which thedoors are suspended and adjusted to conform to their connecting edgesand .to the floor. The recess in the lug or projection H on the underside of the bracket A is elliptieal in form, which admits of anoscillating motion of the bracket A on a line with the axles of wheelsB, thus allowing adaptation of said wheels to any irregularity of thecarriage or track. The rolls B serve to keep the axles of the flangedwheels B at right angles to a longitudinal line of the track E. Theangular plates D are secured to the top and front edges of the doors, towhich the suspension-rods G are adjusted, as explained. The said angularplates maybe made separate, and the perforation in the horizontal partthreaded to receive the threaded bolt 0, in which construction thehorizontal .or vertical part of the plate may be omitted.

Fig. 3 represents the hangers adjusted to a single door, with theguide-rolls B of the rear hanger omitted and the flanged wheels B ofsaid hanger placed under and against the track. The guide B at bottom ofdoors, Figs. 1 and 2, is substituted by the roller S and the track G.The door is suspended and moved by the front top and bottom rollers, therear top roller serving as a guide, and preventing the lower roller frombeing thrown from the track,

which track is within the recess between the walls.

A single wheel, with or without flanges, may be used in lieu of wheelsB. It the flanges are omitted, the wheel can travel upon a way or withina groove upon the under side of said track.

Fig. 5 represents an elastic buffer for attaching to the back edges ofdoors, which resists a violent shock in opening or closing them andprevents thembeing drawn too far into the doorway. The buffer iscomposed of the plates I and J rubber K, and the cylindrical head L,which parts are connected together by the rivet M, which is securedrigidly to or forms a part of plate I, which plateis secured to the rearedge of door. The plate J has an excess of weight on the perforated end,which weight keeps it in a horizontal position against the projection N.The ends of plate J project beyond the sides of doors, interceptingprojections provided in the walls of the building, thereby preventingthe door from running too far into the opening, as heretofore explained.NVhen the door is placed in position between the walls the plate J canbe moved to a horizontal position by inserting a knife between the sideof the door and the edge of the jamb, into the nicks O, or by means ofastringfastened in the perforation P. The stop J can be turned into avertical position by simlar means, when the door can be moved from therecess. The guide R at bottom of door, Figs. 1 and 2, is secured tofloor even with side of door-jamb, which guide fits into the groove inbottom of door and prevents swaying of the same.

In the construction of the hangers I prefer to use hard-wood trackandiron wheels, with their axle-beariu gs hushed with anti-frictionmeta-l.

It will be observed from the foregoing that the carriages actindependentof each other, and that I use a single track made with theleast waste of material, and that the elements constituting the hangersare constructed with a view to perfect working and economy of expense.The doorway is clear of obstructions and the appendages out of sight.The door can be readily adjusted at any time to conform to anyirregularity of the frame or floor. In view of these facts, myiuventionpossesses important advantages over other hangers.

Having explained my invention, what I claim is- 1. A pair of brackets, AA, united at their lower ends, as described, and provided with Verticaland horizontal arms, the latter having suitable guides or rolls actingon the opposite outer vertical faces of a single track, a pair ofwheels, 13 B, having their hearings in said brackets and traversing theopposite sides of the top of the track, a suspensionrod, and a means ofconnecting it with the slidingdoor,

when these various elements are combined, constructed, and arranged tooperate as and for the purpose described.

2. The brackets A A, united at their lower ends by an arm having acentral vertical perforation and a transversely-recessed lug orprojection on its under side, in combination with and for the passage ofa suspension-rod, whereby the latter is free to swivel within said arm,the wheels B B allowed a lateral play, and the longitudinal tipping ofthe door prevented, substantially as set forth.

3. The screwthreaded angular attachingplate D, the threadedsuspension-rod, made to swivel as described, the pair of united bracketsA A, with their vertical and horizontal arms, and guide-rolls B B,andthe wheels B 13, all combined and arranged as specified.

4. Asliding door-having an angular threadedattaching-plate,D,sunkthereinand secured to the top thercof,incombination with a threaded suspension-rod, made to swivel as described,and a pair of united brackets, A A, the connecting-arm of which isperforated and provided with a laterallyrccessed lug on its under side,constructed to operate for the purpose set forth.
